  • Network as a Service

    A NaaS platform implemented as a cloud-native set of Java-based microservices on a foundation of Spring Cloud and Activiti/Flowable workflows. I started as the lead back-end developer and covered the DevOps workflows and tools in collaboration with another developer. I also developed an Angular-based GUI for admin tasks.

    We followed an Agile software development process with a two-week cadence. As I grew the team to 17 developers, covering development, test engineering, build automation, and SRE, I gradually shifted out of day-to-day development tasks but made sure to stay hands-on and on top of the new technologies introduced.

  • Business Analytics and Dashboards

    A set of business dashboards that provides insight into how the business is doing in terms of sales versus directly related costs of the hosting infrastructure.

    The implementation involved creating ETL processes in Python that collect data from HubSpot, AWS, OCI, GCP, Azure, and Alibaba, and populate tables in a Redshift-based data warehouse. Several SQL scripts and stored procedures create roll-up views of the raw data. Last but not least, the dashboards are implemented using Google Data Studio. To handle the amount of data and drastically improve performance, the largest dataset gets exported to and imported into Google BigQuery.

  • NetFoundry ServiceNow Demo

    Self Service Network Access Request: Example Integration: ServiceNow

    This integration demonstrates how to implement an integration with NetFoundry's NaaS REST API using ServiceNow. Using this feature, an enterprise can seamlessly integrate zero trust access into their onboarding process for new employees.
